伏牛山区水土流失危害严重,实施水土保持生态修复是加快区域水土流失防治步伐的有效措施。针对大区域生态修复工程建设亟待解决的适宜性区划问题,采用主导因子分级组合及其专题图叠加分析法,对伏牛山区生态自然修复的适宜性进行评价与分区。1)提出地貌类型、土地覆被类型和地面坡度3个主导因子作为生态自然修复适宜性评价与分区指标,并对其进行分级(分类)和分区;2)按照实施封禁保育(促进生态自然修复)措施的适宜程度,提出“适宜”、“暂不适宜”和“不适宜”3个生态自然修复适宜性等级,并确定其区域分布格局;3)将伏牛山区的生态自然修复适宜性划分为2个大区(一级区)、4个亚区(二级区)和15个类型区(三级区)。研究结果可为伏牛山区水土保持生态自然修复工程的规划布局提供技术支撑。
Soil and water loss in Funiu Mountain Area is seriously harmed, and implementing ecological restoration of soil and water conservation is an effective measure to speed up the prevention and control of soil erosion. Aiming at the problem of suitability zoning to be solved urgently in the construction of ecological restoration engineering in large area, the suitability of zoology natural restoration in Funiu mountain area is evaluated and partitioned by the hierarchical combination of dominant factors and the overlay analysis of thematic maps. 1) Put forward three dominant factors of landform types, land cover types and ground slope as ecological suitability assessment and zoning indicators, and classify them and classify them; 2) According to the implementation of banned conservation (promote natural ecological restoration ), And put forward three ecological natural restoration suitability criteria such as “suitable”, “not suitable for temporary” and “not suitable for”, and determine the regional distribution pattern; 3) The suitability of ecological restoration is divided into two large areas (first level area), four sub-areas (second-level area) and 15 types of area (third-level area). The results can provide technical support for the planning and layout of the natural restoration project of soil and water conservation in Funiu Mountain.
